Here's why:
* Microscopic size: Microbes are extremely tiny, measured in micrometers (µm). For reference, a human hair is about 50-100 µm in diameter.
* Limitations of human vision: The human eye can only see objects about 0.1 mm in size or larger.
To see microbes, you need a microscope:
* Light microscope: These use lenses to magnify the image of a sample, allowing you to see the shape and structure of microbes.
* Electron microscope: These use electrons to create a magnified image, providing even higher resolution and allowing you to see the internal details of microbes.
